DETAILED DESCRIPTION OF VARIOUS ASPECTS OF THE DISCLOSURE

The following discussion presents various aspects of the present disclosure by providing examples thereof. Such examples are non-limiting, and thus the scope of various aspects of the present disclosure should not necessarily be limited by any particular characteristics of the provided examples. In the following discussion, the phrases “for example,” “e.g.,” and “exemplary” are non-limiting and are generally synonymous with “by way of example and not limitation,” “for example and not limitation,” and the like.

As utilized herein, “and/or” means any one or more of the items in the list joined by “and/or”. As an example, “x and/or y” means any element of the three-element set {(x), (y), (x, y)}. In other words, “x and/or y” means “one or both of x and y.” As another example, “x, y, and/or z” means any element of the seven-element set {(x), (y), (z), (x, y), (x, z), (y, z), (x, y, z)}. In other words, “x, y and/or z” means “one or more of x, y, and z.”

The terminology used herein is for the purpose of describing particular examples only and is not intended to be limiting of the disclosure. As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “includes,” “comprising,” “including,” “has,” “have,” “having,” and the like when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Thus, for example, a first element, a first component or a first section discussed below could be termed a second element, a second component or a second section without departing from the teachings of the present disclosure. Similarly, various spatial terms, such as “upper,” “lower,” “side,” and the like, may be used in distinguishing one element from another element in a relative manner. It should be understood, however, that components may be oriented in different manners, for example a semiconductor device may be turned sideways so that its “top” surface is facing horizontally and its “side” surface is facing vertically, without departing from the teachings of the present disclosure.

Various aspects of the present disclosure provide an electronic device (e.g., a semiconductor device) and a manufacturing method thereof, including a stable support structure for semiconductor die and/or other electronic components that for example suppresses or inhibits warpage.

Various aspects of the present disclosure provide an electronic device including a first semiconductor die (e.g., a single die, a stack of die, etc.) having a top surface or side (e.g., a planar top surface) and a bottom surface or side (e.g., a planar bottom surface) and including first conductive pads on the bottom surface, a second semiconductor die (e.g., a single die, a stack of die, etc.) spaced apart (e.g., laterally apart) from the first semiconductor die and having a top surface or side (e.g., a planar top surface) and a bottom surface or side (e.g., a planar bottom surface) and including second conductive pads on the bottom surface, an encapsulant (e.g., molding material or other encapsulating material) encapsulating side surfaces of the first semiconductor die and the second semiconductor die, and a carrier attached to the top surfaces of the first semiconductor die and the second semiconductor die and providing support for the first semiconductor die and the second semiconductor die.

In accordance with various aspects of the present disclosure, the carrier may, for example, be or comprise silicon (Si). The carrier may also, for example, be or comprise metal. Such metal may, for example, have a lower thermal coefficient of expansion (TCE) than copper (Cu). The carrier may, for example, comprise a thickness greater than 100 μm. The carrier may also, for example, comprise a thickness greater than 75 μm. The carrier may, for example, be coupled to (e.g., directly coupled to, indirectly coupled to, attached to, etc.) the top surfaces of the first and second semiconductor dies with adhesive (e.g., an adhesive layer).

In an example implementation, the first semiconductor die may be or include a logic chip (e.g., a processor die, controller die, co-processor die, application-specific integrated circuit die, programmable logic die, discrete logic die, etc.) and the second semiconductor die may be or include one or more memory chips.

In an example implementation, the electronic device may further include interconnection structures (e.g., solder balls or bumps, metal posts or pillars, pads, leads, wires, etc.) electrically and/or mechanically connected to the first conductive pad and the second conductive pad.

In accordance with various aspects of the present disclosure, the electronic device may include a substrate (e.g., an interposer, etc.) on the bottom surfaces of the first semiconductor die and the second semiconductor die and having a top surface or side (e.g., a planar top surface) and a bottom surface or side (e.g., a planar bottom surface), wherein the substrate includes conductive vias (e.g., straight through vias, redistribution layer(s), conductive paths comprising multiple conductive layers and vias, etc.) passing through the substrate from its top surface to its bottom surface. Each of the conductive vias may, for example, be electrically connected to a respective one of the first conductive pad and the second conductive pad. Such electronic device may further include interconnection structures (e.g., solder balls or bumps, metal posts or pillars, pads, leads, wires, etc.) electrically and/or mechanically connected to the conductive vias.

Various aspects of the present disclosure provide a method of manufacturing an electronic device (e.g., semiconductor device, etc.), the manufacturing method including coupling (e.g., directly coupling, indirectly coupling, attaching, etc.) a first semiconductor die (e.g., a single die, a stack of die, etc.) and a second semiconductor die (e.g., a single die, a stack of die, etc.) to the top surface of a substrate (e.g., an interposer, etc.), the first semiconductor die having a top surface or side (e.g., a planar top surface) and a bottom surface or side (e.g., a planar bottom surface) and including first conductive pads on its bottom surface, and the second semiconductor die spaced apart from the first semiconductor die, having a top surface or side (e.g., a planar top surface) and a bottom surface or side (e.g., a planar bottom side) and including second conductive pads on its bottom surface, encapsulating side surfaces of the first semiconductor die and the second semiconductor die using an encapsulant, attaching a carrier to the top surfaces of the first semiconductor die and the second semiconductor die, and removing the substrate.

In accordance with various aspects of the present disclosure, the carrier may, for example, be or comprise silicon (Si). The carrier may also, for example, be or comprise metal. Such metal may, for example, have a lower thermal coefficient of expansion (TCE) than copper (Cu). The carrier may also, for example, comprise a thickness greater than 100 μm. The carrier may, for example, be coupled to (e.g., directly coupled to, indirectly coupled to, attached to, etc.) the top surfaces of the first and second semiconductor dies with adhesive (e.g., an adhesive layer).

The removing of the substrate may include removing some or all of the substrate in any of a variety of manners (e.g., by grinding, thermal releasing, mechanical peeling, chemically etching, etc.). Such removing may, for example, expose the first conductive pad and the second conductive pad to the outside.

The manufacturing method may, for example, include attaching interconnection structures (e.g., solder balls or bumps, metal posts or pillars, pads, leads, wires, etc.) to the first conductive pad and the second conductive pad.

Various aspects of the present disclosure provide a method of manufacturing an electronic device (e.g., an semiconductor device, etc.), the manufacturing method including coupling (e.g., directly coupling, indirectly coupling, attaching, etc.) a first semiconductor die (e.g., a single die, a stack of die, etc.) and a second semiconductor die (e.g., a single die, a stack of die, etc.) to the top surface of a substrate (e.g., an interposer, etc.), the first semiconductor die having a top surface or side (e.g., a planar top surface) and a bottom surface or side (e.g., a planar bottom surface) and including first conductive pads on its bottom surface, and the second semiconductor die spaced apart from the first semiconductor die, having a top surface or side (e.g., a planar top surface) and a bottom surface or side (e.g., a planar bottom surface) and including second conductive pads on its bottom surface, encapsulating side surfaces of the first semiconductor die and the second semiconductor die using an encapsulant, attaching a carrier to the top surfaces of the first semiconductor die and the second semiconductor die, thinning (e.g., back grinding, etc.) a bottom surface of the substrate, and forming conductive vias (or other conductive signal distribution structures) through the thinned substrate.

In accordance with various aspects of the present disclosure, the carrier may, for example, be or comprise silicon (Si). The carrier may also, for example, be or comprise metal. Such metal may, for example, have a lower thermal coefficient of expansion (TCE) than copper (Cu). The carrier may also, for example, comprise a thickness greater than 100 μm. The carrier may, for example, be coupled to (e.g., directly coupled to, indirectly coupled to, attached to, etc.) the top surfaces of the first and second semiconductor dies with adhesive (e.g., an adhesive layer).

In the thinning of the substrate, the substrate may for example be thinned to have a thickness of about 10 μm to 30 μm. In the forming of the conductive vias (or other signal distribution structures), vias passing through the substrate (e.g., formed after the thinning, formed prior to the thinning for example in a back end of line (BEOL) redistribution structure forming process, etc.) from the top surface to the bottom surface of the substrate may be formed and the vias may be filled with a conductive material.

The manufacturing method may, for example, include attaching interconnection structures (e.g., solder balls or bumps, metal posts or pillars, pads, leads, wires, etc.) to the conductive vias.

As described above, in an electronic device in accordance with various aspects of the present disclosure, a carrier may be formed on a first semiconductor die and a second semiconductor die, thereby inhibiting or suppressing warpage while stably supporting the first semiconductor die and the second semiconductor die. Such a carrier may also, for example, efficiently emit heat generated by the first semiconductor die and the second semiconductor die to the outside.

The above and other aspects of the present disclosure will be described in or be apparent from the following description of various example implementations. Various aspects of the present disclosure will now be presented with reference to accompanying drawings, such that those skilled in the art may readily practice the various aspects.

FIG. 1 shows a flow diagram of an example method 1000 of making an electronic device, in accordance with various aspects of the present disclosure. The example method 1000 may, for example, share any or all characteristics with any other method discussed herein (e.g., the example method 3000 of FIG. 3, etc.). FIGS. 2A-2E show cross-sectional views illustrating example electronic devices and example methods of making an electronic device, in accordance with various aspects of the present disclosure. The structures shown in 2A-2E may share any or all characteristics with analogous structures shown in FIGS. 4A-4C. FIGS. 2A-2E may, for example, illustrate an example electronic device at various stages (or blocks) of the example method 1000 of FIG. 1. FIGS. 1 and 2A-2E will now be discussed together. It should be noted that the order of the example blocks of the example method 1000 may vary without departing from the scope of this disclosure.

The example method 1000 may, at block 1010, comprise coupling a first one or more electronic components (e.g., one or more semiconductor dies) and a second one or more electronic components (e.g., one or more semiconductor dies) to a substrate. The electronic components may, for example, be presented herein in the form of semiconductor dies. Such presentation is for illustrative purposes and not for limitation. For example, the electronic components may comprise active components, passive components, digital components, analog components, hybrid analog/digital components, etc.

The first and second semiconductor die(s) (or electronic components) may comprise any of a variety of characteristics, non-limiting examples of which are provided herein. For example, the first one or more (e.g., at least one) semiconductor die may comprise a single die, a vertical stack of multiple dies, etc. In a stack implementation, each die of a stack of die may for example be coupled to each other utilizing any of a variety of structures (e.g., conductive through-silicon via (TSV) structures, etc.). The first one or more semiconductor dies may include a top surface (e.g., a planar top surface, etc.), a bottom surface (e.g., a planar bottom surface, etc.), and a plurality of side surfaces (e.g., planar side surfaces, etc.) between the top surface and the bottom surface. Also, each of the first one or more semiconductor dies may include a top surface (e.g., a planar top surface, etc.), a bottom surface (e.g., a planar bottom surface, etc.), and a plurality of side surfaces (e.g., planar side surfaces, etc.) between the top surface and the bottom surface. The second one or more semiconductor dies may also comprise a single die, a vertical stack of multiple dies, etc. The second one or more semiconductor dies may include a top surface (e.g., a planar top surface, etc.), a bottom surface (e.g., a planar bottom surface, etc.) and a plurality of side surfaces (e.g., planar side surfaces, etc.) between the top surface and the bottom surface. Also, each of the second one or more semiconductor dies may include a top surface (e.g., a planar top surface, etc.), a bottom surface (e.g., a planar bottom surface, etc.), and a plurality of side surfaces (e.g., planar side surfaces, etc.) between the top surface and the bottom surface.

The first semiconductor die(s) and/or the second semiconductor die(s) may, for example, be or comprise silicon or semiconductor material. For example, the first and/or second semiconductor die(s) may comprise logic circuitry (e.g., discrete logic circuitry, processor circuitry, application specific integrated circuitry, programmable logic circuitry, etc.), memory circuitry (e.g., random access memory, read only memory, EEPROM circuitry, flash memory circuitry, memory stick memory, etc.), analog circuitry, digital and/or analog power supply circuitry, hybrid analog/digital circuitry, etc.

The first semiconductor die(s) may, for example, include one or more first conductive pads. Such first conductive pads may, for example, be on the bottom surface (or bottom side) of the first semiconductor die(s). Similarly for example, the second semiconductor die(s) may include one or more second conductive pads. Such second conductive pads may, for example, be on the bottom surface (or bottom side) of the second semiconductor die(s). Note that in an example implementation in which a stack of dies are utilized, each die of the stack may have such conductive pads. The conductive pads may, for example, be or comprise copper, aluminum, nickel, silver, gold, any of a variety of conductive metals or other materials, any combination thereof, etc. Note that the first conductive pad(s) of the first semiconductor die(s) and the second conductive pad(s) of the second semiconductor die(s) may be on other sides of their respective die(s) and/or may be on different respective sides of their respective die(s).

The substrate may comprise any of a variety of characteristics, non-limiting examples of which are provided herein. For example, the substrate may comprise a circuit board material (e.g., FR-4 glass epoxy, G-10 woven glass and epoxy, FR-n with n=1 to 6, CEM-m with m=1 to 4, laminate, laminate thermoset resin, copper-clad laminate, resin impregnated B-state cloth (pre-preg), polytetrafluoroethylene, combinations thereof, equivalents thereof, etc.). The substrate may comprise one or more layers of any of a variety of dielectric materials, for example inorganic dielectric material (e.g., Si₃N₄, SiO₂, SiON, SiN, oxides, nitrides, etc.) and/or organic dielectric material (e.g., a polymer, polyimide (PI), benzocyclobutene (BCB), polybenzoxazole (PBO), bismaleimide triazine (BT), a molding material, a phenolic resin, an epoxy, etc.), but the scope of the present disclosure is not limited thereto. The substrate may, for example, comprise silicon or any of a variety of semiconductor materials. The substrate may also, for example, comprise a glass or metal plate (or wafer). The substrate may be any of a variety of configurations. For example, the substrate may be wafer or panel form. The substrate may also, for example, be in diced or singulated form. The substrate may also be referred to herein as an interposer.

The substrate may, for example, be or comprise a bulk material with no conductive routing paths. Alternatively for example, the substrate may comprise one or more conductive layers, vias, and or signal distribution structures. For example, the substrate may, for example, comprise conductive vias extending into the substrate from the top surface thereof to or toward the bottom surface thereof. For example, the substrate may comprise a single or multi-layer signal distribution structure (e.g., in example implementations in which the entire substrate is not later removed, etc.).

The first one or more semiconductor dies and the second one or more semiconductor dies may be positioned laterally (e.g., horizontally) apart from each other. There may, for example, be an empty space between the first die(s) and the second die(s). In an example implementation, there might be no electronic components mounted to the substrate between the first die(s) and the second die(s). Note that although only two sets of one or more semiconductor dies (or components) are discussed herein for an electronic device, this is for illustrative clarity only and not limitation. For example, a third one or more semiconductor dies, a fourth one or more semiconductor dies, etc. may also be coupled to the substrate and also spaced laterally apart from the other die (or components). The spacing of such die (or other electronic components) may, for example, be one-dimensional along a single line or two-dimensional (e.g., in a two-dimensional matrix form looking down on the substrate). A third-dimension may, for example, be provided by component stacking.

At this point, the top surface of the first one or more semiconductor dies may be coplanar with the top surface of the second one or more semiconductor dies. The top surface of the first one or more semiconductor dies may have the same height above the substrate as the top surface of the second one or more semiconductor dies. This need not, however, be the case. As will be discussed herein, if coplanarity of such top surfaces is desired and not provided during the coupling process, a planarization process may be performed. Note also that one of more of the lateral sides of the first one or more semiconductor dies and of the second one or more semiconductor dies may be planar and parallel with each other.

Block 1010 may comprise preparing the die (or other component(s)) and/or substrate for the coupling process. Such preparing may, for example, comprise receiving the die and/or substrate from an upstream manufacturing process, receiving the die and/or substrate from shipping, etc. Such preparing may, for example, comprise forming or otherwise preparing interconnection structures on the die (or components) and/or substrate. Such preparing may, for example, comprise dicing or singulating the die. Such preparing may, for example, comprise forming signal distribution structures where needed. Such preparing may, for example, comprise performing cleaning, planarizing, etc.

Block 1010 may comprise coupling the first and second semiconductor die (or other electronic components) to the substrate in any of a variety of manners, non-limiting examples of which are provided herein. For example, block 1010 may comprise coupling (or attaching) the semiconductor die to the substrate utilizing a layer of adhesive (e.g., applying a preformed adhesive tape or sheet or film, printing or otherwise depositing a layer of liquid or paste adhesive, etc.) to the substrate and/or the dies, and then positioning the dies. For example, the adhesive may entirely coat the top side of the substrate and/or might only coat the bottom sides of the dies. The adhesive may, for example, comprise a releasable adhesive (e.g., a thermally and/or chemically releasable adhesive, a light-releasable adhesive, etc.). Also for example, block 1010 may comprise utilizing a reflow process to attach the semiconductor dies to the substrate. As discussed herein, the substrate may be prepared in the form of a wafer or panel of such substrates, but may also be prepared in single form.

An example implementation 200A showing various aspects of block 1010 is shown at FIG. 2A. The example implementation 200A (or assembly, sub-assembly, package, etc.) comprises a substrate 260′. The first semiconductor die 110 comprises first conductive pads 111 on a bottom surface (or side) thereof. The first semiconductor die 110 is coupled (or attached) to the substrate 260′ with a first adhesive layer 119.

The example implementation 200A also comprises a stack of second semiconductor dies 120 comprises a top stacked die 120 a and a bottom stacked die 120 b. The top stacked die 120 a and the bottom stacked die 120 b are electrically and/or mechanically coupled to each other (e.g., utilizing a reflow process, utilizing conductive adhesive, etc.). Conductive paths 122 (e.g., conductive vias, conductive through-silicon vias, general signal distribution structures, etc.) provide electrical connectivity between the stacked die and/or between any or all of the stacked die and the second conductive pads 123. There may also, for example, be an underfill 121 between each of the stack of second semiconductor dies 120.

The bottom stacked die 120 b comprises second conductive pads 123 on the bottom surface (or side) thereof. The second semiconductor die(s) 120 is coupled (or attached) to the substrate 260′ with a second adhesive layer 129. Note that the first adhesive layer 119 and the second adhesive layer 129 may be separate adhesive layers that correspond to their respective semiconductor dies. In another example implementation, however, the first adhesive layer 119 and the second adhesive layer 129 may be respective portions of a single continuous adhesive layer (e.g., formed on the substrate 260′ prior to placement of the first semiconductor die(s) 110 and second semiconductor die(s) 120). In such an example implementation, there may also be adhesive on the top surface of the substrate 260′ laterally between the first semiconductor die(s) 110 and second semiconductor die(s) 120.

In the example implementation 200A, the top surface (or side) of the first one or more semiconductor dies 110 is coplanar with the top surface (or side) of the top stacked die 120 a. The top surface of the first one or more semiconductor dies 110 has the same height above the substrate 260′ as the top surface of the second one or more semiconductor dies 120. As explained herein, this need not be the case, for example at block 1010, and if such coplanarity is desired, a planarization process may be performed at some point during the method 1000.

Block 1010 generally comprises coupling a first one or more electronic components (e.g., one or more semiconductor dies) and a second one or more electronic components (e.g., one or more semiconductor dies) to a substrate. Accordingly, the scope of this disclosure should not be limited by characteristics of any particular type of electronic component (or semiconductor die), any particular type of substrate, and/or any particular manner of coupling such components to the substrate.

The example method 1000 may, at block 1020, comprise encapsulating the electronic components and/or substrate of block 1010. Block 1020 may, for example, comprise performing such encapsulating in any of a variety of manners, non-limiting examples of which are provided herein.

Block 1020 may, for example, comprise forming encapsulating material to cover at least any or all lateral side surfaces of the first one or more semiconductor dies and the second one or more semiconductor dies. For example, the top and bottom surfaces (or sides) of the first one or more semiconductor dies and of the second one or more semiconductor dies may remain uncovered by the encapsulating material. Block 1020 may also, for example, comprise forming the encapsulating material to cover a top surface (or side) of the first semiconductor die(s) and/or of second semiconductor dies(s). Block 1020 may further, for example, comprise forming the encapsulating material to cover a top side of the substrate 260′ (e.g., portion of the substrate 260′ not already covered by the components. The encapsulating material may, for example, directly contact such covered surfaces, but there may also be one or more intervening layers of material. In an example scenario in which the substrate 260′ is in wafer form, block 1020 may comprise covering the top side of the wafer (e.g., all or at least portions of the wafer on which components are mounted, etc.) with the encapsulating material.

The encapsulating material may, for example, protect the encapsulated components (or encapsulated portions thereof) from external environmental conditions. As discussed herein, the encapsulating material may also provide a base on which to mount a carrier and/or other components.

The encapsulating material may comprise any of a variety of encapsulating or molding materials (e.g., resin, polymer, polymer composite material (e.g., epoxy resin with filler, epoxy acrylate with filler, or polymer with a proper filler), etc. Block 1020 may comprise performing the encapsulating in any of a variety of manners (e.g., compression molding, transfer molding, liquid encapsulant molding, vacuum lamination, paste printing, film assisted molding, etc.).

In various example implementations presented herein, the encapsulating material may have a top surface that is coplanar with the top surfaces of the first one or more semiconductor die(s) and the second one or more semiconductor die(s). Such an example configuration may be formed during the encapsulating or after the encapsulating. For example, in an example implementation, block 1020 refrains for forming encapsulating material on the semiconductor die top surfaces. In another example configuration, block 1020 comprises forming the encapsulating material over the top surfaces of one or more of the semiconductor dies, and then comprises performing a thinning process (e.g., grinding, chemical-mechanical planarization or polishing (CMP), etching, etc.) to planarize the top surface of the encapsulating material and/or the top die surfaces.

An example implementation 200B showing various aspects of block 1020 is shown at FIG. 2B. The example implementation 200B (or assembly, sub-assembly, package, etc.) comprises an encapsulating material 130. The encapsulating material 130 is shown encapsulating or covering lateral side surfaces of the first semiconductor die(s) 110, lateral side surfaces of the first adhesive layer 119, lateral side surfaces of the second semiconductor die(s) 120, lateral side surfaces of the second adhesive layer 129, and the top side of the substrate 260′.

In general, block 1020 may comprise encapsulating the components and/or substrate of block 1010. Accordingly, the scope of this disclosure should not be limited by characteristics of any particular amount of encapsulating, particular encapsulating material, and/or particular manner of performing the encapsulating.

The example method 1000 may, at block 1030, comprise coupling a carrier to at least the top surface (or side) of the first one or more semiconductor dies (or electronic component(s)) and/or the top surfaces (or side) of the second one or more semiconductor dies (or electronic component(s)). Block 1030 may, for example, comprise permanently coupling (or attaching) the carrier. For example, the carrier may be a part of the completed electronic device. Block 1030 may comprise performing such carrier coupling in any of a variety of manners, non-limiting examples of which are provided herein.

Block 1030 may, for example, comprise coupling the carrier to a top surface of the first one or more semiconductor dies and/or to a top surface of the second one or more semiconductor dies. As discussed herein, the top surfaces of such semiconductor dies may be exposed to the outside from the encapsulating material formed at block 1020. Block 1030 may comprise coupling the carrier to such exposed top surfaces. Block 1030 may also, for example, comprise coupling the carrier to the top surface of the encapsulating material formed at block 1020. In an example implementation, block 1030 may comprise coupling the carrier in a wafer or panel form, and thus the entire top surface of the electronic device (or a wafer comprising multiple electronic devices) may be covered by the carrier.

The carrier may, for example, provide support when the substrate is removed (or thinned) at block 1040. Such support may, for example, be beneficial after completion of the electronic device. The carrier may also assist with the dissipation of heat generated by the die (or components) of the completed electronic device. In various example implementations, however, the carrier material may be selected with an emphasis on support or structural stability, rather than heat dissipation. For example, the carrier may be or comprise a material having a relatively low coefficient of thermal expansion (CTE) even if it has relatively poor thermal conductivity, for example rather than a metal having high thermal conductivity.

In an example implementation, the carrier may be or comprise silicon (or other semiconductor material). Such a carrier material may, for example, provide support while generally matching the coefficient of thermal expansion (CTE) of the semiconductor dies (or components) coupled at block 1010. Such a silicon carrier might, for example, comprise only bulk silicon. Also, such a silicon carrier may comprise one or more electrically conductive or heat conductive pathways (e.g., vias) therethrough.

In another example implementation, the carrier may be or comprise metal. In such an example implementation, the carrier may be or comprise a metal having a lower CTE than copper (Cu). The carrier may, for example, prevent or inhibit warpage from occurring due to a difference in the CTE between the carrier and each of the first one or more semiconductor dies (or components) and the second one or more semiconductor dies (or components).

In an example implementation, the carrier may have a thickness greater than 100 μm and less than 150 μm. In another example implementation, the carrier may have a thickness in the range of 50 μm to 100 μm.

Block 1030 may comprise coupling (or attaching) the carrier in any of a variety of manners. For example, block 1030 may comprise attaching the carrier utilizing adhesive (e.g., a layer thereof). Block 1030 may comprise forming a layer of adhesive on the carrier and applying the carrier. Block 1030 may also (e.g., instead of or in addition to forming a layer of adhesive on the carrier) comprise forming a layer of adhesive on the top surfaces (or sides) of the first one or more semiconductor dies, second one or more semiconductor dies, and/or the top surface of the encapsulating material.

Block 1030 may comprise forming the layer(s) of adhesive in any of a variety of manners. For example, block 1030 may comprise applying a preformed adhesive tape or sheet or film. Also for example, block 1030 may comprise printing or otherwise depositing an adhesive paste or liquid. Block 1030 may, for example, comprise forming the adhesive on a wafer or panel (e.g., a wafer or panel of the carrier, a wafer or panel of electronic device assemblies, etc.). In various example implementations, the adhesive may comprise a permanent adhesive. Note that block 1030 may, for example, comprise utilizing a different adhesive than utilized by block 1010 for the die (or component) attachment, but this need not be the case.

Block 3045 may then, for example, comprise filling such apertures with conductive material (e.g., metal plating, solder paste, etc.). Such conductive vias are thus exposed at the bottom surface of the thinned substrate (e.g., for later connection to interconnection structures).
